vtkOpenGLGlyph3DMapper (OpenGL2 version in VTK 6.3) crash
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
If a glyph indexing is set up, but, for some reason, the input data set does not contain the index array, vtkOpenGLGlyph3DMapper::RebuildStructures only initializes the first cell in numPointsPerSource, leading to a crash during entry->PickIds.resize(numPointsPerSource[cc]) with cc > 0.
I believe all values in the numPointsPerSource array should be initialised to 0 in any case. BTW, why not use a vector instead of this unsafe array? The constructor would take care of the initialisation to 0, and there would be no need for explicit deletion.
